Embodiment Construction
[0049] The present invention will be further described in detail below in conjunction with specific embodiments.
[0050] figure 1 A specific implementation flow of the video-based face tracking and recognition method of the present invention is given. In step (2), a face detection operation is performed on the decoded video frame image. The present invention adopts the features of the local binary pattern (Block-Local Binary Pattern, BLBP) with regional weights (face images and non-face images) to be introduced into the AdaBoost face detection framework. LBP is an operator that describes the contrast relationship in the local area of an image. Its calculation formula is as follows:
[0051] LBP P , R = Σ i = 0 P - 1 s (...
